Comment 51 for bug 50031

I see this on a T42p. Starts to shut down, but the fan stays on, and I'm unable to do anything except hold down the power button until it shuts off. I've disabled sleep entirely until then. Reverting to 2.6.15-23 did not help, so my first guess is that -25 is only part of the story. I am now completely up to date on everything that is installed, and still no luck.

I'll help in any way I can, but while I'm comfortable digging into SIGSEGVs, ACPI stuff is not something I have any familiarity with. I'm going to -x all the ACPI scripts and see where that gets me.
